WBMR-G54 Wireless ADSL Router User Guide

Static IP Address

When the Router is configured to use Static IP Address assignment for the WAN connection, you must manually assign

a global IP Address, Subnet Mask and Gateway IP Address used for the WAN connection. Most users will also need to

configure DNS server IP settings in the

DNS Configuration

window (see below). Follow the instruction below to

configure the Router to use Static IP Address assignment for the WAN connection.

To configure a Static IP Address connection, perform the steps listed below. Some of the settings do not need to be

changed the first time the device is set up, but can be changed later if you choose. See the table below for a description

of all the settings available in this window.

WAN Settings window - Static IP

To configure a Static IP type connection for the WAN, follow these steps:

1.

Choose the

Static IP Address

option from the

WAN Settings

pull-down menu.

2.

Under the

ATM VC Settings

at the top of the window should not be changed unless you have been instructed to

change them. However, if you are instructed to change the

VPI

or

VCI

values, type in the values assigned for

your account. Leave the

PVC

and

Virtual Circuit

setting at the default (

Pcv0

and

Enabled

) values for now. This

can be used later if you are configuring multiple virtual circuits for your ADSL service. For more information on

ATM VC Settings, see the table on page 41 below.

3.

Under the

Static IP

heading, choose the

Connection Type

from the pull-down menu. This defines both the

connection type and encapsulation method used for your ADSL service. The available options are

Bridged IP

LLC

,

Bridged IP VC-Mux

,

Routed IP LLC

,

Routed IP VC-Mux

or

IPoA

. If have not been provided specific

information for the Connection Type setting, leave the default setting.

4.

Change the

IP Address

,

Subnet Mask

,

Gateway Address

and (if available)

Secondary DNS

Server IP address

as instructed by your ISP. These are the global IP settings for the WAN interface. This is the “visible” IP address

of your account. Your ISP should have provided these IP settings to you.

5.

Leave the

MTU

value at the default setting (default =

1400

) unless you have specific reasons to change this (see

table below).

6.

NAT

should remain

Enabled

. If you disable NAT, you will not be able to use more than one computer for

Internet connections. NAT is enabled and disabled system-wide, therefore if you are using multiple virtual

connections, NAT will be disabled on all connections.

7.

The

Firewall

should remain enabled for most users. If you choose to disable this you will not be able to use the

features configured in the

Firewall Configuration

and

Filters

window located in the

Advanced

directory. See

the next chapter for more details on these windows.

8.

Most users will not need to change

ATM

settings. If this is the first time you are setting up the ADSL connection

it is recommended that you leave the

Service Category

settings at the default values until you have established

the connection. See the table on page 40 for a description of the parameters available for ATM traffic shaping.

9.

When you are satisfied that all the WAN settings are configured correctly, click on the

Apply

button.

10.

The new settings must be saved and the Router must be restarted for the settings to go into effect. To save and

reboot the Router, click on the

Tools

directory tab and then click the

System

button. In the

System Settings

window, click the

Save and

Reboot

button under Save Settings and Reboot the System.

11.

Click

OK

when the following “Save and restart?” dialog box opens.

12.

The Router will save the new settings and restart. Upon restarting the Router will automatically establish the

WAN connection.

Static IP Parameters

Description

Connection Type

This specifies the connection type and the encapsulation method used for

your Static IP Address connection. The options available are

,

,

,

or

.

IP Address

This is the permanent global IP address for your account. This is the

address that is visible outside your private network. Get this from your ISP.

Subnet Mask

This is the Subnet mask for the WAN interface. Get this from your ISP.

Gateway Address

This is the IP address of your ISP’s Gateway router. It provides the

connection to the Router for IP routed traffic that is outside your ISP’s

network. That is, this will be the primary connection from the Router to

most of the Internet. Get this IP address from your ISP.

Primary DNS Address

This is the IP address of the first choice for Domain Name Service (DNS)

used to match the named URL web address used by most browsers with

the actual global IP address used for a web server. Usually this will be a

server owned by the ISP. Get this IP address from your ISP.

Secondary DNS Address

This is the second choice for a DNS server. Get this IP address from your

ISP.

MTU

The Maximum Transmission Unit size may be changed if you want to

optimize efficiency for uploading data through the WAN interface. The

default setting (

bytes) should be suitable for most users. Some user

may want to adjust the setting to optimize performance for wireless traffic

or when low latency is desired (such as with Internet gaming). It is highly

recommended that the user research how adjusting the MTU may affect

network traffic for better or worse.

NAT

Network Address Translation may be enabled or disabled with the pull-

down menu. Keep in mind that disabling NAT allows on a single computer

to be used for Internet access through the Router. NAT is enabled and

disabled for the Router on all connections (i.e. Pvc0 – Pvc7) if your Router

is set up for multiple virtual connections.

Firewall

Use this to universally enable or disable the Firewall and Filter features

available in the Router. If you disable this you will not be able to configure

settings in the

Firewall Configuration

window or the

Filters

window in

the

Advanced

directory.

ATM Traffic Shaping

The ATM settings in the WAN Settings windows for the different connection types can be used to adjust QoS

parameters for ADSL clients. This may not be available to all ADSL accounts.

ATM Settings for WAN connection

Additional ATM settings for PPPoE or PPPoA connections:

ATM Parameters

Description

Service Category

The ATM settings allow the user to adjust ATM Quality of Service (QoS) or

traffic parameters to suit specific traffic requirements. For applications or

circumstances where packet loss or packet delay is a concern, ATM QoS can

be adjusted to minimize problems. For most accounts, it will not be

necessary to change these settings. Altering QoS settings can adversely

affect performance of some commonly used Internet applications.

If you plan to change QoS or traffic parameters, contact your ISP or

network services provider for information on what types of adjustment are

available or possible for your account. Your ISP may not support the class

of service you want to use.

To adjust ATM QoS parameters, select one of the Service Categories listed

here and type in the PCR value in the entry field below. For the VBR service

category, an additional parameter (SCR) must also be defined.

– Unspecified Bit Rate, this is the default category used for general-

purpose Internet traffic where normal levels of packet loss and delay are

acceptable. For some applications or for multiple connection accounts, it

may be desirable to specify the PCR.

– Constant Bit Rate, usually used in circumstances where very low

packet loss and very low Cell Delay Variable (CDV) are desirable.

– Variable Bit Rate, usually used when network traffic is characterized

by bursts of packets at variable intervals, and some moderate packet loss

and delay is acceptable. This category is typically used for audio and video

applications such as teleconferencing. The network must support QoS Class

2 to use VBR.

PCR

Peak Cell Rate – The PCR is inversely related to the time interval between

ATM cells. It is specified for all three service categories (UBR, CBR and

VBR) in Kbps.
